MECHANISTIC INVESTIGATION OF REFLECTION CRACKING OF ASPHALT OVERLAYS

In this paper, a mechanistic approach to the study of reflection cracking is discussed, and the limitations of empirical methods of analysis are briefly reviewed. Based on the concept of mixed-mode fracture, it is shown that, for the analysis of reflection cracking, the concept of a strain-energy-density factor is more applicable since it considers provisions for incorporating the effect of other modes of fracture. Theoretical analysis using a prismatic finite element program has been used to verify the postulated mechanisms. In addition, the results of laboratory experiments on model overlay structures are presented and indicate that the hypothesis of mixed-mode fracture is relevant. /Author/
